A uniform thin flat isolated disc is floating in space. It has radius `R` and mass `m` . A force is applied to it at a distance `d = (R/2)` from the centre in the `y`-direction. Treat this problem as two-dimensional. Just after the force is applied:

A

acceleration of the centre of the disc is `F//m`.

B

angular acceleration of the disk is `F//mR`.

C

acceleration of leftmost point on the, disc is zero

D

point which is instantaneously unaccelerated is the rightmost point.

Text Solution

Verified by Experts

The correct Answer is:
A, B, C
`F=ma`……….i

`F R/2=1/2mR^(2)alpha`…………ii
`aP=a-alphaR=0`
